EPDM O-Rings & Seals
Ethylene-propylene is a copolymer of ethylene and propylene (EPM), or, in some cases, a terpolymer due to the addition of a diene monomer (EPDM). EPDM O-rings have great weathering resistance. A special characteristic of EPDM is its resistance to certain brake and hydraulic fluids (including Pydraul® and Fyrquel and Skydrol®).
EPDM O-rings and seals have a good resistance to steam. It needs to be taken into consideration that EPDM is not suitable with most hydrocarbons, such as oils, gasoline, kerosene and petroleum oils.
